The first widely publicized example of online advertising was conducted via electronic mail. On 3 May 1978, a marketer from DEC (Digital Equipment Corporation), Gary Thuerk, sent an email to most of the ARPANET's American west coast users, advertising an open house for a new model of a DEC computer. Despite the prevailing acceptable use policies, electronic mail marketing rapidly expanded and eventually became known as "spam."
We’ve all heard those horror stories about folks who accidentally published personal content to their employers’ social media channels -- a marketer’s worst nightmare. So to avoid publishing mishaps like those, assign Facebook Business Page roles only to the employees who absolutely need it for the work they do each day. And before you do that, be sure to provide adequate training to those who are new to social media management, so they aren't confused about when they should be hitting "publish," what they should be posting, if something should be scheduled first, and who they should be posting it as.
